JAR LIFTER Filed June 30, 1943 I I INVENTOR.

B add ml W Patented Nov. 23, 1943 UNETED STATES .PATEN'E OFFICE 1 Claim.

This invention relates to jar lifters which are intended to embrace or partially embrace the neck or other portion of a jar having a flange or bead to be engaged by segmental jaws carried by arms. The jar lifter comprises an integral or one-piece structure of preferably resilient metal such as wire, the jaws of which may be separated by a pull oppositely on the arms so that the said jaws are sufllciently far apart to embrace the neck of the jar in order that when the arms are released they carry the jaws into engagement with the neck of the jar under the aforesaid bead or flange, so that by lifting the aforesaid instrumentality the jar may be moved into or from a receptacle Where the contents of the jar is being treated, such as a boiler or the like, employed in canning processes.

It is a further object of the invention to provide a lifter of the character indicated in which the arms and a cross member or handle are formed integral and so related that when the arms are separated, torsion develops in the handle which is suificient to move the arms together, as aforesaid, after they are separated; and furthermore, the lifter is strong and durable and comparatively inexpensive to produce and maintain.

With the foregoing and other objects in View, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawing forming part of this application, wherein like characters denote corresponding parts in the several views, and in which:

Figure 1 illustrates a view showing a front elevation of a jar lifter embodying the invention;

Figure 2 illustrates a view thereof in a position at right angle to that in which it is shown in Fig. 1; and

Figure 3 illustrates a perspective View of the jar lifter collapsed.

The implement comprises a length of spring or resilient wire or other metal, in which the central portion forms a cross bar or handle 5 and from the opposite ends of which, pairs of arms are formed, one arm 6 extending downwardly and bent to form into a portion 1 which is approximately horizontal and then extended upwardly to produce the arm 8, which arm 8 is shaped into an eye 9 that embraces the bar or handle 5 and hinges on the said bar. The portion 7 is curved so that it will embrace a neck or other portion I!) of a jar and it will coact with the other arm formed as an integral part of the bar.

In the production of the coaoting arm, the bar is extended to produce a downwardly extending portion ll of the arm and the material is then extended horizontally as at l2 on the approximate plane of the portion 7 of the first described arm. The material is then extended upwardly, as at l3 and terminates in an eye M which encircles the arm and oscillates thereon.

The arms of each pair on the two ends of the handle or bar have oppositely extending finger pieces 15 and [6 which are grasped by an operator for moving the arms apart for carrying the jar-embracing elements clear of the neck of the jar, so that when they are released they will spring into engagement with the neck of the jar, as shown in Fig. 2. The horizontally disposed segmental portions of the arms may be termed jaws as they serve to embrace and clamp against the neck of the jar. The movement of the jaws into engagement with the jar is brought about by the torsional action of the handle or bar when it is twisted in effecting the movement of the jaws.

From the description it is obvious that when the handles [5 and l 6 are forced apart, each carries a respective arm and therefore the jaws are separated, and when released the torsional action of the metal causes the jaws to engage the jar, which jar may then be lifted by grasping the bar or handle 5.

I claim:

A jar lifter comprising a length of resilient metal, the central portion of which is shaped to form a handle, arms at the ends of the handle, each arm comprising a downwardly extending length of material, a horizontally extending central portion and an upwardly extending terminal portion at the end of the horizontally disposed portion, the said upwardly extending portion having an eye embracing the bar at the end opposite that from which the said arm is a part, the two arms being separable for clearing the neck of a jar to be lifted, and finger pieces integral with and extending oppositely from each of the pair of arms for manipulating the arms for embracing the neck of a jar.
